CDI記錄器注入異常

Question

我有以下服務：

@Singleton
@Startup
public class VideoFeedService {

    @Inject
    private Logger logger;

    @PostConstruct
    public void start() {

        //do stuff
    }
}

我在哪里注入從此類產生的記錄器：

public class Resources {

    @Produces
    public Logger produceLog(InjectionPoint injectionPoint) {
        return Logger.getLogger(injectionPoint.getMember().getDeclaringClass()
                .getName());
    }
}

我在部署時遇到以下異常：

我正在使用Java 8，Java EE 7並將其部署在Wildfly服務器上。 我還使用了JBoss快速入門中Kitchensink示例中使用的標准pom.xml，它與Logger基本上具有相同的作用。 知道我在做什么錯嗎？

Answer 1

您沒有提供有關beans.xml文件的信息。 在Java EE 7（CDI 1.1）中，您不必放一個（默認情況下CDI是激活的），但是，僅發現具有bean定義注釋的bean 。 您的Resources類沒有定義定義注釋的Bean（沒有明確的作用域注釋要簡短），因此可能未發現您的生產者。

我建議您在自己的Resources類上放置一個@ @Dependent ，EJB總是作為CDI bean被發現，因此無需向您的VideoFeedService添加范圍。
